Trojan horse Dropper.Generic_c.MMI

I am having an issue with an apparent trojan horse virus detected by my antivirus program, AVG Anti-Virus Free 2012. The problem started earlier today, and seems to have occured after I installed a suddenly appearing update for Adobe Flash Player, which I ignorantly accepted. Since then, each time I start up my computer, the desktop icons are rearranged to the left as though the arrangement has been reset, and I have been getting the following warning from AVG Resident Shield frequently:

It should be noted that the process name and -ID were different at first, but after searching Google for a while, I found a recommendation of installing AVG PC Tuneup, which would supposedly solve the issue with the desktop icons. However, after installing and using the program, the warning from AVG Reisdent Shield started appearing even more frequently and is reappearing at least three times per minute as I am writing this post, with the process name and -ID changed to the ones displayed above. I do not remember what the initial name and ID were, nor do I know where to find this.

The frequent warning stirred me to search around the internet for possible solutions, concluding that many others are experiencing this issue and that it is likely because of a virus installed by the (fake) Adobe Flash Player update. The issue does not seem easily resolvable and most people were requested a lot of complicated information that I did not understand too well. Several people were advised a quick fix through "cmd.exe", but they reported recurring of the virus within a day, and therefore I did not attempt this. Elsewhere, a guide explained how to remove a "services.exe virus", telling me to go to the Task Manager and find services.exe in the Processes tab, but it was not listed there.

Furthermore, I am using Windows 7 and AVG Anti-Virus Free 2012. I have installed every recent update for both the operating system and the anti-virus program, and have performed several scans with AVG, each showing services.exe as a white-listed trojan horse virus, with the message "All problems have been solved." I have no idea what to do, and it seems to be getting out of hand, so I hope any of you can help me with this problem!

It should also be noted that this morning, when I turned on the PC again (I posted last night), AVG immediately detected another 'virus', which it supposedly removed, called "C:\Windows\Sysnative\RUNDLL32.EXE. During the aswMBR scan, it warned me about two other infected files which also could not be removed safely, called "C:\Windows\assembly\GAC_64\Desktop.ini" and "C:\Windows\assembly\GAC_32\Desktop.ini. I received the same warning during the ESET Online Scanner scan.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic461583.htmlyou should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic. Good luck with your log.
